3.2-mJ, 1.5-μm laser power amplifier using an Er,Yb:glass planar waveguide for coherent Doppler LIDAR

چکیده
We developed a 1.5 μm eye-safe wavelength high-gain and high-average power laser amplifier using an Er,Yb:glass planar waveguide for coherent Doppler LIDAR. Applying the planar waveguide structure, high-average output power with near single transverse mode was realized. Consequently, high-gain and high-efficient operation were achieved by multi-bounce optical path configuration. Amplifying the pulsed signal light at 1550 nm, the maximum pulse energy of 3.2 mJ was achieved at the repetition rate of 4 kHz. High energy output from this amplifier is expected to extend the measurable range of coherent Doppler LIDAR.

Wind profile is fundamental in many atmospheric phenomena. Most of the weather stations are on land, while the stations on the sea are very sparse. Present global three-dimensional wind data is not good enough to improve numerical weather prediction, the global climate model, and many other meteorological studies. Spaceborne infrared and visible imagers and microwave scatterometers can make win...

A novel and compact diode-pumped Er-Yb:glass laser, with single-frequency output power up to 20 mW in a wavelength range from 1531 nm to 1547 nm, was frequency stabilized with respect to sub-Doppler rovibrational transitions of C2H2. The laser frequency was locked to these molecular lines by means of the non-linear wavelengthmodulation spectroscopy technique. The relative frequency stability of...
